FIBER-GUIDE FOR COMBING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 363,794, dated May`31, 18817.

Applicniion led March 20, 1886. Serial No.106,021. (No model.)

. To all whom it may concern:

Beit known that I, ISAAC BEST, a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented a new and useful Fiber- Guide for CombingdVIachines, of which the following is a specification.

My invention relates to improvements in wool-combing-machine attachments, and my object is to increase thc bulk of clean longstaple wool drawn, from the large circle of combs.

To accomplish this result my invention consists in au adj ustabiy-attached shield of thin metal, which I designate as a wool ber guide.7 Said guide may bein form rectilinear, with one of its ends pierced with two or more slots for the reception of bindingserews, while the remaining or forward end is separated into two flaps or arms, the lower one of which (when the guide is vertically adjusted) is inwardly reliexed to form a stationary roll, which may be strengthened or re-enforced by a round bolt secured thereto by stay-pins. rIhe lower corner of the upper unbended fiap is rounded to offer no impediment to the passage of the wool ber. The otherwise con.- formation of said ber-guide is arbitrary, depending upon the method of adjustment and its relation to the combs.

Further improvements in detail are illustrated in the annexed drawings, forming a part of this specification, in which Figure 1 indicates a view in perspective of my improved ber-guide co-operating with a section of the comb-bed of a wool-combing machine having vertical drawing-rollers. Fig. 2 is a side elevation of the exterior face of my berfguide. Fig. ,3 represents a longitudinal central section (on line x, Fig. 2) of the same. Fig. 4 exhibits a section of the parts as would appear when in operation.

Similar letters refer to like parts throughout the several view thereof, referring to which- A designates my improved fiber-guide, the upper projecting arm, B, having a semicir cular foot, C, to permit the unimpeded progress of the wool ber as it rotates with the combs ID. The lower arm, being inwardly re- -exed, forms the stationary roll E, which may be reenforced or strengthened by the bolt F,

secured thereto by stay-pins G G. Slotted ap` ert-ures H H permitthe guide A (in the practical application of myinvention to the Noble woolcombing machine) to be perpendicularly attached to the inside of the bracket I, sustaining the presser-feed plate J, by screw-bolts K K entering said slots H H, or in any convenient manner, so that the stationary roll E of said guide may rest in juxtaposition to the approaching peripheries of the perpendicular drawing-rolls L and M, which form at the junction of their perimeters-a re-entering or curvilinear angle, as at N, Fig. 4. One side of said angle is formed by the belt or comb apron O, and within this angle said stationary roll E, as a part of the guide A, is situated. In this position the long beard or ber P I? of the wool, unmixed with noils, is drawn along by the surface of the comb-apron O, appreaching the curved nose or foot C of the upper arm, B, of Said guide, passes under said arm, and on coming in Contact with the stationary roll E is pressed so closely against the opposing sides and directly toward thecenters of said revolving drawing-rolls L and M as to practically' draw out the long ber close to the combs of the large circle, and thereby increase the production of said machine by decreasing the beard or ber after escaping the action of said rolls, as observed at Q, Fig. 4, while the lon g-staple wool is carried by the belt through the ordinary channels to the roving-cans.

In the practical operation of combing the wool occurrences are frequent where the product is to some extent drawn above or over the combs or pins, and thereby escapes their action. The above result is entirely obviated in the present invention, as the position of the project-ing arm B is such that it overrides theber, confining it to the combbed, and particularly below the points of the comb contiguous or in proximity to said arm. This feature I consider appertains to no other simi lar invention, and completely eradicates the tendency of the upper surfaces of the wool to escape disintegration.

The resultant operation of my improved attachmcnt is an increase in the bulk of longber cleandrawn wool to nearly double the amount obtained before its introduction and an increased eifectiveness of the drawingrolls, while the advantages of a stationary or resist- `modified to the exclusion of the round bolt and stay-pins Without detraetiug from its capacity or departing from the spirit of my invention.

Having described the construction and operation of my improved fiber-guide, what I desi re to seen re by Letters Patent, and claim, isl. The standard I, the presser-feed plate J, the circleconib D, and drawing-off rolls L M, combined'with the fiber-guide A, having a reflexed arm, forming a iiXed roll, E, and a projectingarm, B, the elliptic foot C, and the apertures I-I H, and the conning screw-bolts K K, substantially as and for the purpose specified.

2. The adjustable fiber-guide A, having a retlexed arm enwrapping a bolt, F, forming the stationary roll E, a curved arm, B, and the adj usting-apertures H II, and screw-bolts K K, in combination with the circle-comb D, drawingoif rolls L M, standard I, and feed plate J, as illustrated and described.

3. The ber-guide A, formed with an arm, B, and having the apertures H H, the standard I, and the screws K K, whereby said guide is adjustably secured to the standard I, combined with the comb D, comb-apron O, drawing-off rolls-L and M, and feed-plate J, snbstantiall y as set forth. Y

In testimony whereof I'liave signed this specification in presence of two subscribing:r witnesses.

ISAAC BEST.
